Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475474, here are decompositions:

3 + 31475471 = 31475474
31 + 31475443 = 31475474
67 + 31475407 = 31475474
73 + 31475401 = 31475474
103 + 31475371 = 31475474
157 + 31475317 = 31475474
223 + 31475251 = 31475474
367 + 31475107 = 31475474

Showing the first eight; more decompositions exist.
